Functional Testing | Types | Methodology  

In this video, We have discussed about Functional Testing, its significance, types and methodologies of functional testing.
Key Points on Functional Testing:
Definition: Validates software against functional requirements/specifications.
Objective: Ensure the application behaves as expected and meets defined requirements.
Types of Functional Testing:
Unit Testing: Tests individual components for correctness.
Integration Testing: Checks interfaces between different modules.
System Testing: Tests the complete system as a whole.
User Acceptance Testing (UAT): Validates the system with real users.
Test Cases: Involves writing test cases that specify input, action, and expected output.
Black Box Testing: A technique where the tester does not need to know internal workings.
Automation: Can be automated using tools like Selenium or QTP.
Defect Detection: Identifies defects early, reducing fixing costs later.
End-User Perspective: Ensures the software meets user expectations and performs intended functions.
Test Environment: Requires a suitable environment that mimics production for accurate results.
Documentation: Essential for tracking testing progress and ensuring quality assurance.
